[Hydrogen buildup at Fukushima? What does it mean & why does it happen?](http://vimeo.com/32233482) from [Fairewinds Associates](http://vimeo.com/user6415562) on [Vimeo](http://vimeo.com).

TEPCO recently discovered hydrogen buildups within the containment buildings in Fukushima Units 1, 2 and 3. Could there be another explosion, and if so how? Fairewinds conducts a laboratory experiment to show that if oxygen is present with hydrogen in a nuclear power containment, a deflagration explosion might occur.
